IRAC Monitoring of NGC 4051 for Interday Variability: Using the Spitzer Space Telescope for a 10 day infrared monitoring of the region around the supermassive black hole at the center of the galaxy NGC 4051 to help determine the dust distribution around it.

Abstract

We will be observing the Seyfert 1.5 NGC 4051 on a daily basis for approximately 10 days for signs of variability at 3.6 and 5.8 microns. NGC 4051 has previously shown variability on this timescale at 2.2 microns. Based on the difference in variability at 3.6 and 5.8 microns limits can be placed on the dust distribution at the nucleus of the AGN.
